Does your listening/reading stamina improve over time?

I’m not asking about when you’ve learned Japanese fluently and you can easily reading or watch something that you can enjoy for hours, just like in your native lesson. I mean when you’re actively deciphering stuff in your brain that is properly challenging at your level, are you able to increase how much you’re able to do over time? It seems my limit is like 10-15 minutes if that when listening to or reading something completely in Japanese before my brain is completely overloaded and I have to take a break for several hours or until the next day. I’m not sure if I’ll get to where I can do like an hour+ at some point or if this is just my personal limit and I need to work with that. I’m just now starting to consume japanese media, so I’m going through a lot of mental hoops with listening and reading things that are at my level. Let me know the answer either from personal experience or with science.
